Los-ROLLING DEVICE.

. Application led June 7, 1913.

To all whom t may concern Be it known that I, ALLAN PAYNE, a subject ofthe King of Great Britain, residing at Courtenay, in the Province ofBritish Columbia and Dominion of Canada, have invented certain new anduseful Improvements in Log-Rolling Devices, of which the following is aspecification. Y

This invention relates to log-rolling devices and more particularly to adevice employed in connection with log carriages used in saw mills orthe like for the turning of the log.

The primary object of this invention is the provision of a device ofthis nature which will materially decrease the amount of labor necessaryfor the turning of logs while upon the carriage of the saw mill andfurther to provide a device of this nature which will turn the logs inany desired direction without necessitating any manual adjustment of thedevice.

Figure 1 is a side elevation of one of the improved log-rolling devicesshowing one of the hooks of the same secured to a log, the log beingshown in dotted lines; Fig. 2 is an enlarged side elevation showing theparts of the log-rolling device in a different position to that shown inFig. 1;` Fig. 3 is a longitudinal sectional view through Fig. 2; Fig. 4is an end view of the device; and Fig. 5 is a cross-sectional viewthrough the logrolling device. Fig. 6 is a perspective view of myimproved log rolling device showing to advantage the frame supportingthe same.

Fig. 7 is an end elevation showing the device in another position.

Referring more particularly to the drawings, 1 designates the cam-shapedcasing which is rigidly mounted upon a shaft 2 by means of a key 4 andwhich has a camshaped member 3 disposed upon one side thereof andloosely mounted upon the shaft 2.

The shaft is supported in bearings 2 carried by beams 3, said beamsforming a part of a frame work of any practical design, said shaft 2being mounted adjacent to the log deck of the saw mill and disposed atone side of the saw, the vobject of the device being to rotate the logfor each cutting operation. Rotation of the shaft y2 is accomplished bymeans of a sprocket 5 0 having a chain 51 passing thereover as shown toadvantage in Fig. 6.

The casing 1 has a hook member 4 pivotally connected thereto as at 5.The hook member 4 has its outer end 6 bent inwardly substantially atright angles to the portion 7 of the member v4 and sharpened as isclearly illustrated in Figs. 1 and 3 of the drawings. This hook member 4is provided forthe turning of the logs toward the casing 1 or to theright-as is illustrated in Fig. 1, a log being shown in dotted lines.The hook member 4 is pivotally mounted upon the casing 1 at 5 by meansof a pin 8 which has an arm 9 formed integral therewith and eX- tendinginwardly into the casing 1. The arm 10 which has one end thereofenlarged as at 11 is pivotally connected to the arm 9 at '12 and forms ameans for the operating of the hook member 4. v

The cam member 3 is held in a desired position by means of a link 39connected to a pin 40 mounted on thecam member 3 and operated verticallyby means of a bell crank lever 41. Each cam member 3 is provided Vwiththis mechanism and each of the bell crank levers is simultaneouslyactuated so as to insure synchorism in the operation of the device.

The cam-.shaped member 3 which is loosely mounted upon the shaft2 has anotch 14 formed therein, which notch 14 is so shaped as to receive theenlarged end 11 of the arm 10 when the cam 3 moves so that the enlargedend 11 of the arm 10 is engaged by the notch 14, as is shown in Fig. lof the drawings.

Then it is desired to operate the hook member 4, the casing 1 and theshaft 2 are rotated, by means of the sprocket 50 and chain 51 until thearms 9 and 10 are in a position as is shown in Fig. 1. The cam member 3being loosely mounted upon the shaft 2 will not rotate therewith byvirtue of its connection with the lever 41 and consequently the enlargedend 11 will, upon rotation of the casing 1 and the shaft 2, seat litself within theV notch 14. This will stop movement of the lever 10 inunison-with the casing 1 and upon further movement or rotation of thecasing 1 and the shaft 2, will by means of the pivoted connectionbetween the same and the arm 9, force the hook member 4 outwardly andcause the sharpened end 6 of the same to engage the log 15. After thetsharpened end 6 of the hook 4 has engaged the log reversing therotation of the shaft and casing will draw the log 15 toward the casing1 or to the right as is indicated in dotted lines in Fig. 1 of thedrawings. A roller 16 is revolubly mounted upon the casing 1 and isengaged when the log is drawn toward the casing 1, by the hook 4 andrests on the casing 1 and ro-ller 16. The log in this position ispractically off the carriage and resting upon the casing 1, with aroller 16 receiving most of the weight. The log slides fromv the roller16 on to the carriage when the casing is turned toward the log.

A plurality of straight bars 20 which have sharpened points 21 formedupon their outer ends are also mounted within the casing 1 and haverollers 22 revolubly mounted, by means of the pins 23 upon their innerends. The rollers 22 are disposed within the interior of the cam-shapedmember' 3 and engage the inner surface of the sides of the same as isclearly illustrated in Fig. 3 of the drawings. A collar 24 is mountedupon the shaft 2 within the cam-shaped member 3 and has the rollers 22engaging the outer surface thereof when the bars 20 are in aninoperative position.

1n Fig. 7 the casing 1 is shown in the position which the same occupieswhen the radial arms 20 are being operatively engaged with a log. Itwill be seen in this view that the arm 10 is resting upon an abutment10', the said abutment 10 preventing the loose swinging and dangling ofthe arm- 10 when inoperative, and the camr member 3 is in the positionshown in Fig. 7.

A member 25 is pivotally mounted upon a pin 26 within the cam-shapedmember 3 and has its end 27 curved so as to fit snugly against the outersurface of the collar 24. The member 25 is normally held in position,having its curved end contacting with the outer surface of the collar24, by means of a flat spring 2S which has one end thereof secured tothe cam-shaped member 3 and the other end engaged by a pin 29 which ismounted within the member' 25. A member 30 is rigidly mounted upon thepin 26 and operates in unison with an arm 31 which is also mounted uponthe pin 26 and disposed upon the exterior of the cam-shaped member 3.The outer end of the arm 31 has a slot 32 formed therein in which isseated a pin 33. The pin 33 has a plate 34 rigidly connected thereto,which plate, at certain times, forms a covering for the notch 14 andprevents the enlarged end 11 of the arm 10 fromv entering the notch 14.When the shaft 2 and casing 1 arev rotated in a direction so as to causethe hook members 4 to operate the plate 34 and the arm 31 are operatedor moved so as to allow the enlarged end 11 to enter the notch 14. Thisoperation causes the member 30 to move against the side of the member 25and move the saine into en-gagement with the outer edge of the cam, thuspreventing the rollers from operating when the casing is turned in anydirection. r1`he spring 23 engaging the member 25will, in connectionwith the pin 29, force the member 25 back to its proper positiondirectly after the rollers 22 have been passed therebetween.

`When the shaft 2 and the casing 1 are rotated in the direction oppositeto that for operating the hook member 4, the spring 23 engages themember 25 and holds the same in a closed or inoperative position and atthe same time causes the member 30 and the arm 31 to form a closure forthe slot within the cam shaped member 3 at 14. This causes the rollers22 to move outwardly along the outer edge of the member 25, as isclearly shown in Fig. 3 of the drawings and causes the bar 2O to moveoutwardly through an opening 36 in the casing 1 and engage the log 15from the under side. This will turn the log 15 to the left or away fromthe casingv 1 and the shaft 2.

As hereinbefore set forth 1 have provided a sprocket 50 mounted upon theshaft 2 and having the ychain 51 operatively engaged therewith forrotating the shaft 2, and when it is desired to throw the arms 4outwardly into engagement with a log, the cam members 3 are retained inthe position shown in Figs. 1 and 6. The shaft 2 is now rotated to theleft, the arm 10 engaging in the cut out portion 14 in the cam 3.Continuing to rotate the cam shaped members 1 will cause the arm 4 toswingoutwardly relative to the cam shaped members 1 by virtue of thestationary f connection of the same through the medium of the arm 10with the cam member 3. 1t is thought that its operation will be clear tothose skilled in the art. 1n order to remove the plate 34 from the pathof the arm 10 the L said plate is connected to and carried by the arm 31as hereinbefore set forth. rl`he arm 31, as shown to advantage in Fig.3, is connected to the member 25, and when the said member 25 is in theposition shown in Fig. 3 the arm 31 will be in the position shown inFig. 7 that is, seating in the cut-out portion 14 of the cam 3. Theplate 34 remains in this position as long as the arms 2O are in use, themember 25 serving to force one of the arms 20 outwardly beyond theperiphery of the cam shaped member 1 as shown to advantage in Fig. 3.lVhen the plate 34 is seated in the cut-out portion 14 it is impossiblevfor the arm 10 to engage in the said cut-ont 'portion' 14 and thereforthe hook members 4 will not be forcedout from the cam shaped members 1when the arms 20 are in use.

The function of the rollers 22 and the arms 20 has been hereinbefore setforth and it is not thought that it is necessary to dwell upon thisfurther.
